Sshd_config[PubkeyAcceptedKeyTypes]: Could not evaluate: Failed to save Augeas tree to file.

[markdv77]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 7.x
• Ruby: bundled
• Distribution: Debian
• Module version: 6.0.0

How to reproduce (e.g Puppet code you use)

Save this as sshd.pp:

sshd_config {
      'PubkeyAcceptedKeyTypes':
        ensure => present,
        #value  => [ '+ssh-dss' ];
        value  => '+ssh-dss';
}

Run using default sshd_config file:

cp /usr/share/openssh/sshd_config /etc/ssh/sshd_config
puppet apply sshd.pp

What are you seeing

Error: /Stage[main]/Main/Sshd_config[PubkeyAcceptedKeyTypes]: Could not evaluate: Failed to save Augeas tree to file. See debug logs for details.

Debug output shows:

What behaviour did you expect instead

I was hoping it would add the option to /etc/ssh/sshd_config

Hi,

I think I fixed this in #65, which is not yet released. Could you confirm that the current HEAD works for you? I expect you will need to swap to the commented line for value in your code:

sshd_config {
      'PubkeyAcceptedKeyTypes':
        ensure => present,
        value  => [ '+ssh-dss' ];
        #value  => '+ssh-dss';
}
